OData - 1:1 Relationships

In Intrexx, references can be made to any data groups. Where the output data group and the referenced data group are both foreign data groups from an OData connection, then a 1:1 relationship can be established between these, provided that a corresponding relationship is defined in the service metadata.

With a 1:1 relationship between two OData foreign data groups (OData terminology: Entity Sets) no primary and foreign keys need to be determined. In OData references, the relationship type is determined and selected directly from the metadata of the OData Service. Thus, for example, the possible relationships between a seminar and a room booking are automatically determined by the OData Adapter from the service metadata and made available for selection. Then click on Next. The data fields required can be selected in the next step.
